APL is well suited to [[image manipulation]] and [[computer animation]], where graphic transformations can be encoded as matrix multiplications. One of the first commercial computer graphics houses, [[Digital Effects (studio)|Digital Effects]], produced an APL graphics product named ''Visions'', which was used to create television commercials and animation for the 1982 film ''[[Tron]]''.<ref>{{cite book |last1=Magnenat-Thalmann |first1=Nadia |last2=Thalmann |first2=Daniel |date=1985 |title=Computer Animation Theory and Practice |url=https://books.google.com/books?id=neGoCAAAQBAJ&pg=PA38 |publisher=[[Springer-Verlag]] |page=38 |isbn=9784431684336 |quote=[[Digital Effects]] is another production house that worked on Tron. They used a laser-scanning system to digitize, store and reproduce images. Judson Rosebush, president of Digital Effects, is the primary designer of APL VISION and FORTRAN VISION, two computer animation packages that are currently used. |access-date=April 3, 2018}}</ref> Latterly, the [https://stormwind.fi/en/ Stormwind] [[Simulation video game|boating simulator]] uses APL to implement its core logic, its interfacing to the rendering pipeline middleware and a major part of its [[physics engine]].<ref>{{cite web |url=https://www.optima-systems.co.uk/stormwind-simulator-dyalog-16 |title=Stormwind Simulator at Dyalog '16 |last1=Gutsell |first1=Sam |date=October 17, 2017 |website=www.optima-systems.co.uk |publisher=Optima Systems |access-date=April 3, 2018 |quote=Stormwind is a [3D boating simulator] that has gained a huge amount of interest in the APL community.}}</ref>

Today, APL remains in use in a wide range of commercial and scientific applications, for example
